I'd like to thank the teams at Packt Publishing and Vaadin. Special thanks to Joonas Lehtinen, Sami Ekblad, Matti Tahvonen, and Marcus Hellberg, who in one way or another influenced this book. Thanks to my friends in Finland and Colombia for their motivation. Last but not least, thanks to my parents and siblings for being so supportive; I genuinely enjoyed writing part of this book with your company.
